In a pair of new modeling studies, researchers examined how policy reform in terms of drug decriminalization (in Mexico) and access to drug treatment (in Russia) might affect two regions hard hit by the HIV pandemic: Tijuana, Mexico and the Russian cities of Omsk and Ekaterinburg.

In a new paper, researchers propose a mechanistic hypothesis that focuses on the potential impact infectious fever has on a particular subset of T cells, known as gamma/delta T cells.

Formation of new blood vessels, a process also known as angiogenesis, is one of the major clinical challenges in wound healing and tissue implants. To address this issue, researchers have developed a clay-based platform to deliver therapeutic proteins to the body to assist with the formation of blood vessels.

In a first-in-humans pilot study, researchers have identified a sentinel area of the brain that may give an early warning before clinical seizure manifestations from focal epilepsy appear. They have also validated an algorithm that can automatically detect that early warning. These two findings offer the possibility of squelching a focal epilepsy seizure — before the patient feels any symptoms — through neurostimulation of the sentinel area of the brain.

Up to now, electronic computer components have been run on electricity, generating unwanted heat. If spin current were employed instead, computers and similar devices could be operated in a much more energy-efficient manner. Researchers have now discovered an effect that could make such a transition to spin current a reality.

Why trust should play a crucial part in the development of intelligent machines for medical therapies.

Researchers have developed a system using artificial intelligence that can edit the facial expressions of actors to accurately match dubbed voices, saving time and reducing costs for the film industry.

When the good and bad bacteria in our mouth become imbalanced, the bad bacteria form a biofilm (aka plaque), which can cause cavities, and if left untreated over time, can lead to cardiovascular and other inflammatory diseases like diabetes and bacterial pneumonia. A team of researchers has recently devised a practical nanotechnology-based method for detecting and treating the harmful bacteria that cause plaque and lead to tooth decay and other detrimental conditions.

A new study tackles an important, unresolved question in the biology of invasive plants. Which is most important to the establishment of new invasive communities — proximity to seed sources, canopy disturbance, or soil disturbance?

From 16 to 66 your personality will change and over time you will generally become more emotionally stable. But don't compare yourself to others; those who are the most emotionally stable when young are probably going to continue being the most stable as they age.
